The mobile site isn’t responding and the desktop site has no mention of it (actually as I was writing this article it is now showing up but not actually working). Is it another curse of the “Black Friday” with too many people trying to access it, or did they just make a mess of it somewhere.
O2 have confirmed on twitter that it is down and are working on getting it back up.
Update – The Argos website is really struggling under the load, as are a number of other sites.
